Abstract

According to the present invention, an input buffer circuit comprises a first and a second buffer circuits operated at different first and second driving voltages and connected in turn, and an output potential control circuit is provided for carrying out a control so that, in spite of the voltage value of the first driving voltage, the threshold of an output potential of the first buffer circuit becomes the threshold of an input potential of the second buffer circuit. Furthermore, the output potential control circuit is configured such that the first buffer circuit is constituted by a pair of complementary current mirror amplifiers, and comprises a feedback control means for carrying out feedback-control to the generation of the output potential for the first buffer circuit based on th output potential on the reference side of this current mirror amplifier.
